EMBOSSlNG-MACHINE.

SPECIFIQATION'forming part of Letters Patent No. 467,175, dated January19, 1892.

Application filed April 22, 1891- Serial No. 389,896- (No model.)

To all whom it may concern.-

Be it known that I, EMILE J AEOK, a citizen of the United States, and aresident of Brooklyn,'in the county of Kings, State of New York, haveinvented certain new and useful Improvements in Embossing-Machines, ofwhich the following is a specification.

This invention relates to improvements in embossing-1nachines,andespecially to devices for feeding the paper to the embossing rollers insuch a manner that the paper is not wrinkled while being embossed.

The invention consists in the combination, with a feed-roller, anembossing-roller, and an impression-roller, of gearing for rotating theembossing roller more rapidly than the feed-roller, a friction-wheel incontact with the impression-roller, and gearing for rotating saidfriction-roller from the shaft of the embossing-roller at a greaterspeed than that of the embossing-roller.

The invention also consists in the constru 0- tion and combination ofparts and details which will be fully described hereinafter, and finallypointed out in the claims.

.In the accompanying drawings, Figure 1 is afront elevation of myimproved embossingmachine, parts being broken out and others shown insection; and Fig. 2 is an end view of the same.

Similar letters of reference indicate corresponding parts. 4

In the drawings, A represents the feedroller, B the embossing-roller,and G the impression-roller, which latter is usually made of more orless yielding material. The shaft D is arranged parallel with and at theside of the embossing-roller, and on the same arms E are hinged, whichcarry at their upper ends a roller F, arranged parallel with and at thetop of the feed-roller A and resting loosely thereon, between whichroller F and the surface of the feed-roller A the paper to be embossedis inserted. The shaft D also carries segmental guide-arms G, theconcave edges of which are close to the surface of the feedroller andact as guides for the purpose of holdingthe paper against thefeed-roller. On the. end of the shaft H of said feed-roller a cog-wheelJ is fixed,thatengages a cog-wheel N, mounted on the shaft M of theembossingroller 13. On the opposite end of the shaft M a cog-wheel L ismounted, that engages a cogwheel 0, mounted on one end of a shaft P,journaled in the lower ends of swinging arms Q, mounted on a shaft R,arranged at the side of and parallel with the embossing-roller B, saidshaft R also carrying curved guides S, the edges of which are close tothe periphery of the embossing-roller B. Arms T project from the mainframe W, and in the same set-screws V are mounted, which rest againstshoulders V of the arms Q, by means of which set-screws V the arms Q canbe adjusted to hold the shaft P a greater or less distance from theembossing-roller B and to produce more or less friction. On said shaft Pa roller U, of rubber or of wood covered with leather or any othersuitable frictional material, is mounted. As the wheel J has a greaterdiameter than the feed-roller A and the wheel N a smaller diameter thanthe embossing-roller B, it follows that the embossing roller is rotatedmore rapidly than the feed-roller A, and thus the paper is drawn fromthe feed -roller upon the embossing roller, and while being so drawn onthe surface of the feed-roller it is stretched and smoothed. The wheel Lrotates the wheel 0 and shaft P at a comparatively high speed, and asthe roller U is in contact with the paper resting on theembossing-roller it serves, by frictional contact with said paper, todraw the paper firmly and smoothly against the surface of theembossing-roller, thereby preventing all wrinkles when the paper passesthrough the embossing-roller upon the impression-roller O. The bestresults are obtained when the proportion of the diameter of the wheel Jis to the diameter of the wheel N as four is to three, and the diameterof the wheel L is to the diameter of the wheel 0 as one is to two. Ifthe roller U is adjusted so as to exert great pressure on theembossingroller, it stretches the paper more than when the roller is soadjusted that it can slip more or less upon the embossing-roller.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. In an embossing-rnachine, the combination, with afeedroller, an embossing-roller, and an impression-roller, ofgear-wheels on the shafts of the feed-roller and embossingroller, thegear-wheel on the shaft of the feedroller having greater diameter thanthe gearwheel on the shaft of the embossing-roller, substantially as setforth.

2. In an embossing-machine, the combination, with a feed-roller, anembossing-roller, and an impression-roller, of a gear-Wheel on one endof the shaft of the feed-roller, a smaller gear-wheel on one end of theshaft of the embossing-roller, a larger gear-wheel on the opposite endof the shaft of the embossing-roller, and a swinging shaft having agear-Wheel engaging with the larger gear-wheel on one end of theembossing-roller, said shaft carrying a friction-roller adapted to bebrought in contaot with the embossing-roller, substantially as setforth.

3. In an embossing-machine, the combination, with a feed-roller, anembossing-roller, and an impression roller, of engaged cogwheels on theshafts of the feed and emboss ing rollers, an additional cog-Wheel onthe shaft of the embossing-roller, a fixed shaft at the side of theembossingroller, swinging arms on said shaft, a rotary shaft on saidswinging arms, a friction-roller mounted on said shaft on the swingingarms, set-screws for adjusting the swinging arms, and a eogwheel on theend of the shaft in the swinging arms, which cog-wheel is engaged by oneof 0 the cog-Wheels on the shaft of the embossingroller, substantiallyas set forth.

a. In an enibossing-maohine, the combination, with a feed-roller, anembossing-roller,

and an iimpression-roller, of gearing on the 35 shafts of the feed andembossing rollers for rotating the embossing-roller more rapidly thanthe feed-roller, a friction-roller in contact with theimpression-roller, and gearing for rotating said friction-roller fromthe shaft 40 of the embossing-roller at a greater speed than that of theembossing-roller, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed myname in pres 45
